Yes you can - or at least you used to be able to. When I flew back from BLR to LHR via DXB at the end of 2104 as I was upgrading at the airport (Y to J) I had to do the two legs separately.
On arrival in DXB at the transit desk I was told I was short a number of miles to book the DXB-LHR leg but could buy them. Which I did. It was a bit of a nerve wracking experience as at the start of the process they said "there's a seat currently available but by the time we finish it may have gone...." As it turned out it hadn't and it was the best Christmas present I ever bought myself.
