You don't have to, no. However, if you beat Red he will disappear from Mt. Silver. If you then beat the elite for again, he will reappear. There is no limit on how many times you can do this, but it won't make his, or the elite 4's Pokemon and different or better.

If you've already won the battle against Red, you may re-challenge him by first beating the Elite 4, and climbing Mt. Silver again. [Heart Gold, Soul Silver] In the original Gold, Silver, and Crystal, you do not need to beat the Elite 4 again. All you have to do is climb Mt. Silver, as many times as you want, and re-battle him. [Original Gold, Silver, Crystal]
