Forum:Relinquished + Super Polymerization

Hi, I was wondering, can you use monsters treated as equip cards with Super Polymerization?

For example, Player A has Relinqueshed with Stardust dragon attached. Player B has Junk Warrior, Super Polymerization and a card to discard with Dragon Knight Draco-Equiste in the Extra Deck. Can Player B use Super Polymerization to Fusion Summon Dragon Knight Draco-Equiste using Junk Warrior and the attached Stardust Dragon?

Thanks :)
