While there is nobody on earth with the authority to remove a Pope, some canonists believe that, if it were established that a Pope was a heretic, he could be “removed” by the College of Cardinals, who would simply recognize that he had already removed himself from office by his heresy.

The Roman Catholic Canon Lawyer in the article says no.

It's an interesting situation to be sure.

Read more carefully. She’s talking about a Pope who is not mentally competent (technically, an “impeded Papal see”), not the case of a Pope who is a heretic. As I said, SOME canonists hold that a Pope can be “removed” for heresy, not all.
