No, and doubt it would ever happen.
During my career I was directly involved in weapon systems development that included some tests that put ridiculous G shock forces on primers, fuses, and “triggers” and can say that there is a huge difference between the forces it would take to set off a primer and the force you get from an inertial bullet puller.
Ever watch one of those slow motion videos of a bunker buster or delayed trigger on a penetrator round. Or, imagine the forces on the triggers and fuses of a shell? I am not trying to say those are identical, but the margin of safety on a small arms primer against G shock is very good when discussing an example of just going for the ride installed in a case. Introduce a firing pin that can punch the cup or have a primer cup slip down into an anvil, and those odds change.
Those compounds and primer designs in rifle and pistol primers would require several orders of magnitude more force to distort or cause a detonation than one could ever arrange from a bullet puller, hand powered or spring actuated.
If a ”loose” primer were able to “slip” in a way that forces an anvil to impact, then the odds can change, but even then it would take such an extreme example of bad fit and higher than conceivable forces from a puller to arrange such an example. (We tried, but with a slam into chamber.)
The hypothetical examples one can imagine to lead to an installed primer being set off with an inertial puller could go on for days, but in the context of motorized machine guns and cannons, those hypothetical extremes were tested and not even a remote risk.
The only thing I will add, is to never leave a primer installed flush or protruding for a semi-auto or auto, cause those slam fire contexts are an actual risk compared to the ones from an inertial puller.

I have pulled bullets with an inertia puller from tens of thousands of surplus ammo rounds without any primer issues. I have also de-primed cases with live primers with no issues. A primer requires a pretty significant strike from the firing pin to detonate. Having said all that, never do anything in a way that your face is behind the primer!

Yes, was a 20 plus year old piece of brass, that spent its life in a die box, for use as a gauge. Have no clue why I thought I might need a gauge for a 22-250, but I made and kept one anyway. Yes later while stream lining my handloading equipment, I found this case, with a bullet and a live primer in it. The bullet had cold welded itself to the case. In my ignorance I loaded it in my inertia puller and started hammering. Could have pushed the bullet in a little deeper with a seating die, but at that time, the thought never occurred to me. Long story short the primer went bang. Gladly no powder was involved. Guess back in the day a single primer was no big deal.

What the heck it works for me !!
Pure gold right there. Thank you !!!
Some military ammo has the bullets sealed with an asphalt like substance that basically glues the bullet to the case neck. To remove those I found a tool at Harbor Freight that I use to wiggle the bullet before using the inertia bullet puller to break the seal.
Brake Line Forming Tool
Amazing deals on this Brake Line Forming Tool at Harbor Freight. Quality tools & low prices.
I had a primer ignite in my inertia puller thats why I asked! I did a search and found this article. Crazy! https://forum.accurateshooter.com/threads/inertia-bullet-puller-mishap.3847327/
and, of course, never try to seat a primer deeper once the round is loaded.

I have heard (not experienced) that using a shell holder in place of the supplied collet in an inertial hammer type puller can do that.

Guaranteed to take the wind out of their sails
I just don't like all that darn noise from the hammers.
