Yes.

Install rootsh or easyroot and then pull up the terminal, type root. Now you're in as the root user.

I have zero experience with it, but you might want to use Emelfm2 since it'll allow you to do some of these removals in a visual method that you might like better. I just... can't say one way or the other for it. In fact, you're using leafpad... it might give you that ability somewhat.

I just don't have either installed.
