Indeed. However, Unix-a-likes do let you delete directory entries for
files that are in use - the file is only deleted when there are no
directory entries for it and no open file handles left. That's not
quite the same, of course, but in unless one is being unnaturally
precise in one's writing it is rare for people to discriminate between
them.

On Windows, on the other hand, my understanding is that you can't delete
a dirent for a file that is in use.

This is technically true - if you 'rmdir' a directory that is some
process's cwd then the dirent will go away but the inode will remain
until it is no longer in use. However, you won't be able to do anything
meaningful with it.
