Not by what I read on the NetBSD FAQ:

Can you reformat TK50 tapes as TK70s (top)
Once you erase a TK50 you can use it in a TK70 drive and vice
versa, but the TK50 and TK70 tape material is different, and the
write current of the TK70 drive is different (lower). This is
not recommended, and should be used for temporary storage for
which you will suffer no pain if lost.

IIRC, the TK50 and TK70 use *exactly* the same media, with a different
format. You can bulk-erase them and reformat them for either.
