Is it possible to load the equivalent of an autoexec.bat file on a thumb drive and have it start executing without any action by the user?

Yes. In fact you can build a "thumb drive" which carries along a simulated keyboard and use it to enter any commands you want, as well as deliver code.

The software that supports USB devices is not designed to be a hardened interface point to a computer.
