Well, factor in the following(needless to say, Spoilers..):

The Tenno were declared lost aboard the Zeriman Ten Zero. Presuming they were kids at the start of THAT voyage, they haven't aged much.

That voyage, long preceded the creation of the Warframes and Transference, along with the end of the Orokin Empire.

In the time between the fall of the Orokin, and rediscovery of the Tenno, the Corpus, Grineer, and Infested rose and fell a few times over, to dominate what remains of the Orokin Empire.

Giving each incident a modest 20 years between the last and the next, that would make the Tenno octogenarians at least. More than likely, they're hundreds, if not thousands of years old, but preserved via Transference and the Somatic Link.
