Looks like Absolute Persistence is only active through Windows as well, like Computrace. Ijust searched for it but couldn't find documentation of it being able to operate through Linux. Have a look for yourself to make sure and if you can't find anything, there's no need to worry.

It can be installed on linux manually, but the persistence doesn’t work last I checked though.
