If CEO changes their mind, then they will look weak and indecisive. So they are unlikely to change their mind. But I have recruiters in my circle and know stories where people challenged rejections and succeeded. All of them were lower level applicants. The hiring managers were overridden by HR or higher level managers. And this whole thing is so rare that whenever it happens I hear about it from my friends.
