Nobody can give you a clear-cut answer. That depends entirely on the resource. But I'd we wary of using anything that touches code added by Lunar Magic if you're not using the latest version. Always keep backups.
I will say however that the ASM mods only enforce compatibility with the latest Lunar Magic. It's entirely possible you may find a resource in the ASM sections in the future that don't work except in LM 3.00+.
