I mean, yes, obviously it's not literally the Arecibo telescope in the same location, but it's a heavy inspiration and quite similar in design and structure. (For example, an obvious difference in BF4 is the surrounding forest, which not as dense as in Puerto Rico's location.)
I would say it takes inspiration from Arecibo over FAST but it's clearly neither. The surrounding topology is flat in comparison to either and there isn't much of a forest to speak of. It's clearly a level design that takes inspiration from reality.
