Power for Ceiling fan power

[Jimi Richards]

If ceiling fan has two switches on the wall but only one is used in fan housing (black is wired to fan and light so one switch turns on fan/light and a remote determines the use and red is capped and 2nd switch is inoperable) can I use that feed(red wire) with shared neutral to wire another fixture (6-10ft away) so I can utilize the unused switch
