Wasn't that a Windows Tablet already? What's the prob? Too much other "bloatware" onboard?
Keep in mind that Linux or their various distros need something like "Wine" or some other loader or compatible emulator. These things while nice and cute are not always fool proof and I wound certainly not trust them to always work! Linus by itself is great but Hal is not a Linux program, as you know.
If you just want nice compatibility and possibly use of Haptek's People Putty (some might want it and some not), then I'd go with an older XP.
Some say their Haptek characters worked fine with Win8 so maybe 10 would work equally well. Can't say how well any of these will port over to your Tablet either way if at all!
Good luck!
