I guess I'll be the first to answer
In lieu of any more qualified answers from people with PS3s, I'd say it's unlikely. I haven't heard of people booting their PS3s from thumbdrives. Besides, the PS3 doesn't boot the operating system directly like your PC does; it actually uses a hypervisor (a kind of small virtualisation operating system) to run the real operating system.
Plus, I believe the Playstation has to be made aware of the existence of the operating system before it will boot it. This involves installing the operating system to the hard disk.
I could be wrong; I don't have a PS3. Your best bet would be to look at Google and see if there's a HOWTO. If there isn't, then it's probably not possible.
