Absolutely! You can use Liquid Chlorine as well! But you MUST use regular, unscented bleach. The anti-splash, gel, scented, etc are all no-nos, but ultra bleach (6% vs 5.25%) or the new super-ultra (8.xx%) are all perfectly fine.

In the water, chlorine is chlorine. Bleach / LC into the water is always OK. The saltwater generator makes chlorine by breaking salt, NaCl into sodium and chlorine, which, when used up, recombine into salt again.

In fact, our SWCG pros here recommend that instead of using your "boost" cycle to shock your pool, use bleach or LC instead to make your cell last longer. I started using an SWCG this year for the first time and used LC whenever I needed to shock it.
