I've already went into detail on why this isn't possible (and provided some background to back the answer up, in hopes credibility will nip it in the butt) but for some reason this still gets useless answers.
It's only possible to “remove” it by having the admin tie removed from the Google admin page and power washing it. Anyone who claims it worked got to keep it and they just removed the management otherwise Chromebooks lock to specific accounts or require a range.
