Can I use GeneratePress to Create and Sell Themes?

I was searching for a starter theme to build on to sell themes - is that what GeneratePress is for?

I searched it and found this quote: GeneratePress is my go to theme for all of my own and client projects. It has proven to be a fast, lightweight and reliable foundation for the websites I build. With GP Premium, my clients were always happy how easy it is to change important parts without relying on others.

If it is possible, can all of the GeneratePress references be changed? Meaning in the theme files:
