I don't think so. Wifi MAC addresses are not being exchanged in 3G/4G
networks. IMEI numbers are not being exchanged in Wifi communications
(my tablet doesn't have an IMEI, for instance). IMEI numbers are
officially being used as personal identifiers. MAC addresses are not.

Changing a Wifi MAC usually has no billing implications. You would want
to change your Wifi MAC address, not to prevent cost, but to gain
(better) privacy.
