Whatever consequences there are derived from the fact that Snow and Charming each have a half of Snow's heart beating in their chests remains to be seen. The writers still have to answer that question. It's one heart but the its two parts of it are seperated. They beat seperately.

I imagine it to be like a living donor transplantation of a liver. If a human liver is donated there's the possibility that you can split the organ in a half providing half an organ for the  patient who is in need of it. If the body accepts the organ the liver begins to heal and starts to grow. In time both halfs will reach normal size. The donor can live with his remaining half. His organ will grow back to normal size, too.

So, I would agree with WinterWoodsGal. Freezing Snow's heart would have no effect on Charming. Freezing Charming would have no effect on Snow.
