Yes! The idea is that you can do anything with NF, including commercial products, as far as you don't just wrapt it and sell it.
In concrete terms, you cannot provide the software or a derivative service "for a fee or other consideration" if the value of what you're providing is "entirely or substantially" from the functionality of the software itself.
But other than that you can do whatever you want. We know of different companies that use NF for their commercial products.
If you have more question I'm happy to help.
