Not necessarily.
Depending on what network software you are using,
if the current setup does not match any of
the previously used interfaces eth0, eth1, etc,
a new interface will probably be created.

You could look at /etc/udev/rules.d/70-persistent-net.rules .
(At least that is the file on my Fedora-8 system.)
