I don't think it's likely that the tyre will be able to slide over the tube unless you add an unreasonable amount of talc - it's probably just stressing the tube. I'd also be concerned that a mineral oil based product would degrade the inner tube. If I had a problem with tyre creep on a fat bike I'd probably try fitting motorcycle rim locks, or some cobbled-together equivalent.
