Not really.  Used by is a reference count that can be incremented by
either dependant modules, or by open devices.  As an example from my
system:

carcharias linux # lsmod
Module                  Size  Used by
ipw3945               102304  1

This is "used" by the user-space ipw3945d daemon.  If I kill that, I
can remove the module...

af_packet              20040  2
arc4                    2048  1
ipt_addrtype            1856  1
ipt_LOG                 5952  1
xt_pkttype              1920  3
xt_tcpudp               3072  4

.. and I have some packet filters setup...

nvidia               4546580  12

...no idea why nvidia requires 12 references for one desktop...

b44                    24140  0

...my wired network card.

To answer the OP, you are allowed to remove the network module of a
configured network interface.  This has the effect of hot-removing the
card, the interface just disappears.
