Most likely the answer is a solid "no" because of the complexity of the handshake protocol required for the cablecard and cable system uses. For example, even if the cablecard and device pair up, copy protection, which is required to decrypt subscribed channels such as hbo, showtime, cinemax, starz, and almost everything else except clear qam, which is like abc, cbs, nbc, fox, cw, upn, pbs, is seperate for exactly the reason your attempting.
Basically what this will mean is that even though the copy protection hasn't been granted you might be able to see those clear qam channels, but thats all.
Idealistically, you'd need a visit from the technician to "pair" the card to the new device and "clear out" the old host ID associated with the card. Once this is done you should be good to go. I did exactly the same thing, was told by Comcast that I could just pop the card into the new device, call them up and tell them the host ID and I'd be good to go.....but it didn't work and still had to have an installer come out.
I hope I was helpful, and good luck dude.
