It might be possible to remove some of the older 05 ones, and some of the older 08 ones; however 05 and 08 are two separate beasts and aren't really properly compatible. I still wouldn't recommend removing any of those though, although if anything did go wrong you can just download them from the Microsoft website here and here.
