In RL Jean Calvin fled from France to Switzerland, where he came in contact with Ulrich Zwingli's teachings. In the aberrated world the french protestants are doing a lot better, and Calvin may not have to flle to what's in the aberrated world is Swabia, and then he might not come in contact with Zwingli's teachings and the reformed faith might not form.
Here's some conclusions, since Luther is getting sanctuary by the Swabians, Swabia will become Lutheran, not reformed, which mean Calvin would work somewhere else, possibly in Brittany or Occitania, since he probably was not chased away from France, but for the reformed faith to form he still need to come in contact with Zwinglis teachings, so we should instead have Zwingli fleeing to france, since his teachings might not be accepted by the earlier Habsburgs.
