As Satellite AV said, as long as you can set the LO frequency you can receive any satellite in any type of polarity. My Pansat 2100A will receive both linear and circular, and C, KU, and DBS frequencies.
Even if you can't set the LO frequency it is still possible to receive all polarities and frequencies. You have to shift the frequencies for the transponders. I found this out when I connected my receiver to a DBS dish at 119w while the receiver was programed for all the IA-5 frequencies and there was signal using one of the FSS frequencies.
It is the LNB that does most of the work. It is what sets polarity and frequency band to receive. The receiver is just there looking for signals to decode.
