Anyways, I guess they are not called Liches in-game or in any books that appear in Skyrim or other games. Mannimarco is called a Lich many times (I haven't played ESO but the information he is one is well known). They just absorb life energy of the Draugr. That could even explain why some Draugr do not wake (but that could also be because a different set of Draugr wakes every time, as the book Amongst the Draugr says). We can say our own definition of liches but the game certainly never mentions the Dragon Priests as being that kind of undead so... I guess they just die if they run out of Draugr. Maybe.
