Apologies if this is a stupid question

Looking on the web it appears that the Virgin flights from MAN to MCO also have a Singapore Airlines flight code. Given that Singapore Airlines are Star Alliance members does this mean I can use my Eurobonus points to book a Virgin flight?

The reason for my confusion is that the MAN to MCO route does not appear on Singapore Airline's website as a timetabled route but Manchester airport's timetable clearly shows a Singapore Airways codeshare.
