"Shock and awe" is today the popular term.
Ultimate Tyranno's effect forces you to attack all of your opponent's monsters with it FIRST. Meaning, if it is in Attack Position, at the beginning of your Battle Phase, it must be the first monster that you attack with, and it must attack all of your opponent's monsters, once each.Because of this, Ultimate Tyranno's effect is not essentially "activated". It has a "continuous" effect, meaning that the effect takes place the second it hits the field. So in answer to your question, it is not a matter of whether you CAN, it is the fact that you MUST utilize its effect during each of your Battle Phases, as long as it is on the field in face-up Attack Position.

Answer taken from the Official English Rulebook: After you've announced your attacking monster and the attack target monster during a Battle Step, the attack target might be removed from the field, or a new monster may be played onto the opponent's side of the field before the Damage Step, due to a card's effect. This causes a "Replay." When this occurs, you can choose to attack with the same monster again, or choose to attack with a different monster, or choose not to attack at all. Note that if you attack with a different monster, the first monster is still considered to have declared an attack, and it cannot attack again this turn.
