Speculation on whether Dangerfield would be permitted to play in the under-18 competition had arisen in recent weeks with reports that several clubs had approached the league to voice their objections.
"Adrian has used his discretion after finding there is no rule in the books saying a draftee cannot play in the TAC Cup," Crows football operations manager John Reid said.
Dangerfield is expected to play with SANFL club West Adelaide up to five times this year before a clearance deadline on June 30.
