No.
To act as an RTK base station you require access to the raw measurements (pesudorage, carrier phase, doppler etc...).
As shown in the document linked below the Max-7Q device on the c027 doesn't support raw data output.
Accepted Answer
MAX-7Q does not support RXM-RAW and RXM-SFRB UBX messages, but the same raw data can be recovered by parsing the undocumented TRK-SRFB(X) and TRK-TRKD5 messages. So the right answer is: c027 can be used for RTK, you only need to bump up the UART speed and write your own UBX-TRK parser. Porting parts of the RTKLIB source code will allow to stream the RTCM3 (or RTCM2 if you really need it) messages over ethernet or wireless modem.
