Is it safe to fully cook a stuffed turkey the night before thanksgiving?
If it was fully cooked properly the first time there shouldn't be any problems at all. You may have an issue with reheating the turkey - not that it would be hazardous to your health, just difficult to do without drying it out or burning it. It might be better to fully carve the turkey and then reheat the meat you want to eat instead of trying to reheat the entire thing.
