Probably already know but just in case you don't have a spare in yours.
Mine has a 120 / 70 / 18 wheel in it - really skinny spare in there at the moment , much thinner than a real wheel, so I would say yes but due to the differences in wheel / tyre profile the boot carpet would be raised up and wobbly, quite a bit.
Suppose you could raise the boot level with polystyrene and put the carpet back down....
