Toilet stack in a 2nd floor flat

Hi We've just bought a 2nd floor flat. There are six flats in the building which was originally built early 1900 I think, and was converted from a nursing home to flats in 2004. There is one toilet in the flat and inside the toilet room is a stack pipe protruding about 4 feet into the room vertically up the corner wall. There's a plastic cap on it. My question is, can we cut this down a few feet so that we can box it in? We have had two different opinions from plumbers - one says you can, the other says leave it. I don't understand why this stack is in the flat at all. We haven't moved in yet as it's not habitable, but this query is slowing down work to get it finished in there. Why are stacks built like that? I've lived in a normal two floor house with 3 loos and haven't seen this. Can anyone shed some light on this for me. thanks thanks Chris. I will make sure it doesn't get chopped and that the proper valve is on top. I'll use the plumber that said to leave it alone.
