Yes, you can prime the beer in your keg just as you do for bottling. Seal it up, purge the oxygen and fill the head space with CO2 and let it sit for a couple of weeks. Hook it up to the CO2 and chill and you're ready to go.
The first glass or two might be full of yeast sediment, just keep pouring them until the beer clears.
