Quite easily and in a few different ways. You can use the "Channel Model" block and just set the frequency offset and nothing else. You can use a frequency xlating filter, or you can do a complex multiply of your signal against a complex sinusoid. Just remember that you need to have a high enough sampling rate to accommodate the bandwidth of your new signal.
