If we think of the Tenno as a military force then maybe the Prime versions of warframes were just higher ranked Tenno? this could also fall into why the Stalker refers to himself as a lower guardian, being another military rank in the Tenno/Orokin military. It's also not clear what the Stalker is (Tenno/Orokin) you could assume he is Tenno because he is able to wear a warframe and use its abilities but it is never said.
