The VM system does keep track of which swap files are in use, it will remove files that are not in use, and when they become "mostly unused", it will attempt to migrate the still valid data in the file to a new file, and remove the old one.

So yes, if you need that space back, the best process is to reboot.

If you delete a swap file yourself on a running system, very bad things will happen, just as if you had removed a RAM DIMM from the running machine.
