Yes you can. There's a number of ways to do it but effectively you will be stood at his 8 o clock (nearest the rail) and using both reins, the outside rein will be tucking in around his hind. You just want a bend at first then back onto track.
It is best if you have another handler at his head to guide him when you first try lateral work. Also it's worth ensuring that he has learned and is able to be truly straight and balanced when doing the straight line work, before you introduce lateral this way.
Another slightly different concept, have you tried chest reining? Again you ca do this with another handler at the head to stop them leaving at first, or use a set of reins and a set of ropes. With Sonny I only need to us just two ropes, but then it was a natural progression from the other things we do.
It has a great balancing effect, and also helps them to halt squarely and balanced. It will of course also help lighten your future rein contact too.
