In general, no. There is a difference between the terms "Dark Magician" and "a Dark Magician monster". The first means a card called, and only called, "Dark Magician", while the second means any monster with 'Dark Magician' in the name, including 'Dark Magician Girl'. That means 'Dark Magician Girl', or 'Skilled Dark Magician', etc, are unable to use most Dark Magician support cards - you can't summon them using Dark Magic Curtain, they won't let you activate 'Dark Magic Attack', etc.
