It does, in it's early stage eg. Ubuntu Touch, but I think there isn't any problem to run other Distros too, at least Android itself is Linux (stock Android is only bad because it's contamined with Google APIs) and Linage OS is an Android fork. The OS isn't a problem, but the question is the compatibility of the needed apps, eg, in profesional ambit, medical apps or other official apps, all of these normally only for Android or iOS.
