Depends on the weight difference, but very potentially yes, and no. Here's why I say that. If you run a lighter car, you're going to need slightly lighter damping to absorb bumps. With this lighter damping, the car will roll more, but the roll potential increase may be offset by the car weighing less.
This is why I tend to not make generic statements. The roll center is the thing you tune last--once you get front/rear weight transfer and camber gain figured out. Where it needs to be is very hard to predict. I like to think of roll center as just the amount of available weight at one end of the car that is also applied to chassis roll.
