It's certainly up to interpretation. Glimfeather the owl called the Green Witch "One of the same crew," referring to the "Northern witches." This could not be possible if they were one and the same. However, this was only a rumor, and no other "Northern witches" are shown in the series beyond the White Witch, who is identified in the Magician's Nephew as rather an Empress of Charn. C.S. Lewis never confirmed (or denied) such a theory, probably because it only became popular after the White Witch and the Green were played by the same person in the BBC adaptations of the books.
