No, the femora in _Cryptovolans_ are long enough (and preserved in such a
position) that I doubt it.
But I'm not sure I see your point--a nonbird theropod could have an effective
leg length just as long as a secretary bird without having such elongated
lower limb elements, since the femur would contribute to the effective leg
length, unlike in modern birds.
