The hardware list should be correct. The ARM machines you linked are Acer Chromebooks 13s (CB5-311), not Chromebook 11s. The 2016 11s are Intel Bay Trail, and supported.

GalliumOS has good-to-very-good support for almost all Intel Chromebooks, but does not support any ARM models yet.

GalliumOS works very well on the 2015 Pixels. It was a lot of work to get there.

And as with all Linux laptops throughout history, you should definitely check the hardware compatibility list first.
