CP business class fares book into discounted business (D on most airlines, C on AC), so it's only restricted as much as that availability is.
It is possible to travel in business (booked in D) on an SQ 380, but they have a specific surcharge related to C/F on the 380 and 77W, and a different surcharge related to the SIN-US nonstops.
