What I want to know is if I can run unity Ubuntu in a tab on my Chromebook.
Because recently I saw one tutorial on 'How-to-Geek' in which they used xfce and did not mention any other versions.

Your question is not clear.
What do you mean by tab in 'run different versions of Ubuntu in a tab'.
It is apparent that your question is about installing two different desktop environment not different version. If I am right, your answer is YES.
How?
If you have unity, simply you can install xfce Desktop Enviroment by this commands:
sudo apt-get install xubuntu-desktop
Then, in login page, you have option to choose to login to which environment.
