Oh, I forgot about Chromebooks and ChromeOS. They are similar, but there are significant differences.
ChromeOS is based on Gentoo. It is centered on keyboard and mouse input, often with touchscreen.
Android is its own flavor of Linux, entirely centered on touch input.
While I think it might be entirely possible to install and remove packages to have one act like the other, we are comparing a different Linux flavor against Android.
Also, my answer is probably generic enough to answer OP.
