Probably. It won't be as fast as SATA, but it took 58 seconds to rsync
my ~ to a USB2 disk just now. 140G of stuff, 125M transferred, and this
is a spinny disk--a flash disk might be faster because of no seek time.

Any x86 from the last 5 years will be able to boot from a USB disk.
USB disks all look like SCSI disks to the kernel. As such, you can plug
the USB disk in, boot from an install CD, and tell that install CD to
use the USB disk as the place to put / and /home and /usr and all those
things.
Note that flash disks may eventually wear out. After 300,000 writes, a
bit cell in a flash disk may not retain its value. Wear-leveling
algorithms in the disk's controller usually mean this doesn't happen
until the disk is many years old. Having swap on a flash disk and using
swap a lot might accelerate this process though--I can't really tell as
I've never put swap on a flash disk.
