Yes. I was able to do it in shifts heating both the tubing and nipple with boiling water and using a needle nose pliers to push the nipple on. Once the nipple was on (barely) I'd submerge both in the water, then push as far onto the tail piece as I could. Rinse and repeat until complete.
A quick and much easier way to do this is with a heat gun. I borrowed my buddy's. Holding the tail piece with needle nose and *briefly* waving the gun by both the end of the tubing and the nipple. Start the nipple on the tubing and briefly wave the heat gun by the tubing to assist with the final push.
Careful with the heat gun though, the first time I used it, I pushed the tail piece right through the wall of the tubing, ripping it open.
