No, leave it as-is.
In many cases, use of the tag no-computers does mean no brute force. But not always! Sometimes it's used to mean, for example, no Googling for solutions.
The spirit of the tag is to solve the puzzle on your own, without the aid of computers. Obviously you will need a computer for some aspects, such as typing in the solution and posting it, but the real point is that you should use your own knowledge or ingenuity. There are various ways you could use a computer for not-in-the-spirit-of-the-puzzle shortcuts:
- brute-forcing possibilities,
- using online word finders,
- searching the web for specific strings/information,
- etc. etc.
Depending on the puzzle and the OP's intent, any of these might be acceptable, and the no-computers tag is there to tell you that it isn't. The tag means different things in different contexts, as may be clarified by the OP in the body of the question.
A tag no-brute-force would only exclude some of these ways to use a computer for "cheating". Sometimes a puzzler wishes to exclude more of them, and the broader no-computers tag better expresses the idea of "just use your own skill" rather than "don't write a program to brute-force all possibilities, but use a computer in any other way you want".
Don't take the tag name too literally: it doesn't exclude things like keeping track of your progress in a text document, which could just as easily be done with pen and paper.
(I'm the one who created this tag, by the way. I dunno if that makes my arguments worth less or more, but I thought I should mention it.)
2021 edit: I've just rewritten the tag wiki to reflect the clarifications in this meta post.
