Everything is possible but you're just complicating your problem.
Why would you identify a category by a piece of text in the Description?
Also, searching in the description as it's text could end to be a slow and unnecessary query, if you have a lot of categories.
To solve it, I recommend you take a look at the documentation about Including & Excluding Categories.
What I would do is to make sub-categories and either hide them manually or do a trick between the child and parent categories.
