CDL isn't an undead. The only undead Dragon Lords are Elder Coffin and Vampiric Dragon Lords as stated by the ST in vol 4 (i think). But it is true, there could be another reason that he can't use wild magic. Maybe when the Ranked magic was put into the world, wild magic was corrupted and is slowly losing power. It would explain why the dragon lords aren't showing themselves as they have been depowered due to the magic corruption.
