Again, not if language is to mean anything.

Maybe you are talking about jargon among certain groups of people or certain professions. I use to work in construction, the words "Caterpiller" and "Bobcat" had very different meanings to us than it might to your average person. If the foremen said, "Get in the bobcat and go move those beams." It would make perfect sense to me, but to somebody who hasn't a clue as to what the word "bobcat" might mean in the context of a construction site would be a bit baffled at the idea of telling someone to get inside of an animal. But even then, the person is probably going to be smart enough to figure out that "bobcat" is being used in a sense that they are unfamiliar with. Thus is the nature of jargon. But the term "bobcat" still applies to something specific in that context, if the foremen decides to make his own interpretation of the word "bobcat" and start using it as a general term to refer to whatever kind of machinery he feel like using that name for, then there will be a breakdown of communication, and his workers will have no idea what he actually wants. However, jargon still fits within the rules of language.

Language means something, when we decide not to follow its rules we only make ourselves out to be idiots, and destroy our ability to communicate in the process.
