Sure, but if you don't know what you are doing, and have a need for lubricating something at home, on a bike, or on a car, you are MUCH better off with a oil, graphite, teflon, or grease.

Sure professionals use WD40 when appropriate. Sure WD40 lubricates great, for seconds to minutes (before the volatilies evaporate off, thus the WD40 smell), less well after that (somewhat gummy residue) and might well stop a creak. But won't lubricate nearly as well as oil or grease or last as long.
