Maybe if it knocks itself down to the ground? But I worry much more about faulty wiring or stuff like that. And that's more a function of the brand and model
Not saying fires don't happen that way but let's say it's a failure mode that is a challenge to achieve intentionally much less accidentally.
Failed FET for instance. They tend to fail "on". Unless you have a highside FET shutting off the power (and that may fail too).
On my printer I have software watchdogs but I also have an entire "dumb" (no MCU) circuit that will shut off a large relay that goes to my heaters if any of it's failsafes are triggered. I have a smoke detector, secondary thermistors, etc.
There are a bit more things in the way of thermal fuses and heaters that are less likely to runaway on the newer commercial printers but I still think people need to take the risk more serious.
I have been building printers and printing since 2011 and I still prefer to not have my printer in my house where the family sleeps, even with the failsafes. It lives out in the shop with plenty of room around/above it in case of a fire.
And if you want to be outright malicious, you can disable maximum temperature control and do the same with much hotter nozzle rammed into the model - and even print an extra burnable model when you are at it!
Or count on the power supply or the wiring catching fire instead due to overload.
