Nothing says Emma's heart can't be removed, just that Emma's magic stopped Cora. I'm certain that Emma thought she could do what Henry did and have it removed by being willing.

Fans conflate headcanon and theories with facts. Emma realized that something stopped Cora, but nothing said that her heart couldn't be removed and there's no reason for Emma to assume that.
