Probably, although don't know for sure. Also, probably, port-channel may only support a manual configuration, i.e. no LACP.
I do recall (?) some years back I wanted to place all an ASR 1001's (I think it was the 1001, definitely not the -X) gig ports into a port-channel (to avoid cost of 10g port license) but ran into some issue. Whatever it was, finally did go with the 10g port license.
