If this Digimon digivolves from a [Yuuko Kamishiro] that was played this turn, can it attack in the same turn?

Official Ruling
No, it can't. Even if a card digivolves from a card that was placed on the field in the same turn, it can't attack during that turn. It can only attack in the turns after it's played.
