edit: reread your question, probably not. Most chromebooks can't have the ROM totally overwritten.

most Chromebooks can run Linux by writing by writing over a sector of the ROM. Most (and probably this laptop) unfortunately can only write to the RW_LEGACY or BOOT_STUB which introduce significant problems. I'd definitely just run crouton for these.

All chromebooks allow to completely overwrite the firmware.

It requires opening the machine though (and then turning a screw), both as a crude security measure (it's not a drive-by attack if it takes 10 minutes of physical access) and a stability guarantee (without the modification, the system basically can't be stuck, no matter how broken an update might be).

Disclosure: I work on Chrome OS firmware.

I suppose I've been reading third party documentation.

Along with the link above indicates otherwise. Are these websites both wrong?

I did completely overwrite the firmware for my Acer c720 (by removing that write protect screw) but I assumed that was an exception.

The write protect screw (or a similar mechanism) exists and works the same way on every Chromebook.
