12" display is a killer requirement here. Lenovo (Duet) and Asus (CM3) make detachable Chromebooks, but neither tops 11". The CM3 has an integrated pressure-sensitive stylus. The HP X2 11 is right at 11" with a pen and dockable stylus, but in a 3:2 aspect ratio. IIRC all modern Chrome OS devices support Linux containers, which probably won't be what you want either, and none of them are remotely very powerful. I don't know about the CM3, but I've installed Ubuntu on the Duet and I can find videos of people installing and running Ubuntu on the x2 with touch working.
