It depends on what you are trying to do. They are the same chip but unfortunately the steps required to enable our full HW/SW co-design workflows are not so simple due to different board layouts etc.
The good news is that as of 2018b, the system objects and blocks we use to transmit and receive data from the board should be compatible with the ADI hardware image that is shipped with the FMCOMMS card. So this would enable you to transmit and receive data, at least.
If you require HW/SW co-design (HDL and C code generation) there would be quite a convoluted process that we wouldn't be able to support you with. I suspect for the time you would spend trying to port over to the ZC702, you may be better placed purchasing a ZedBoard.
