If it runs on Chromebooks does that mean Chromebooks can be made into generic UEFI laptops?

This is interesting given Googlebooks actually use the same boot process as Chromebooks, they just chain into aboot.

Yes. Even before this you could use MrChromebox's UEFI Coreboot on a lot of ChromeOS devices. You can run Linux or even Windows on them.

For Intel/AMD Chromebooks, yes.
