If I was to nitpick, I would only say that load is unlikely to be a problem: walls are usually configurable in office spaces, and floors should be able to handle stuffing a data centre in the middle as well.
It depends on the building. A three story brick & concrete building may be able to handle a data center on the top floor. As you get into the 80 floor skyscrapers you're getting into buildings where you have to start worrying about exactly how they wave in the wind, something I don't tend to think about at all. Trying to stick a datacenter on the 75th floor there may be a noticeably bad idea. Scale isn't just an issue for programmers.
