Technically it is not allowed. If you book as a return flight then the return journey will likely be cancelled. And it is only possible without checked luggage, which would be booked to the final destination. For one way without luggage it's unlikely to be a problem but as a courtesy you should probably tell SQ staff so they don't waste time delaying the flight for you.
