Your Componon is good for the normal range, up to 20x, but this isn't written in stone because it is up to you to decide when it starts to fall apart. If you are going much much larger than that then you are better off using the Micro-Nikkor or getting a lens that is designed for big enlargements like the Rodagon-G. In the end though it will be up to you to decide what is good enough. The most important thing you can do regardless of the lens you use is to make sure your enlarger is properly aligned. I cannot stress that enough.
Personally I would encourage you to do whatever you want. They are your images. I have seen some pretty phenomenal enlargements from normal 35mm like Tri-X. The limit is in the printer not in the film. Don't let anyone discourage you from going large.
