Yes and no.

You can't normally unmount(2) a filesystem that has files open,
unlinked or not, meaning that in order to unmount it you have to get
all the files out of the open-but-unlinked state.

I don't know what happens with umount -f (MNT_FORCE to unmount(2)), but
ISTM that either it clears the files or leaves the filesystem dirty.
