Q:

Should we [uninstall] this tag?

I've come across the uninstall tag. Is it a meta tag that should be burninated?
If it isn't burninated, should it be renamed uninstallation to make it a noun rather than a verb?

A:

This is a meta-tag. It only has meaning in the context of other tags. 

If a question is about uninstalling product X, it should be tagged with X. 
If a question is about tools to generate installers and uninstallers, it should be tagged with the tags for these tools.  
If a question is about problems encountered while manually writing an uninstaller, it should be tagged with tags appropriate to that problem. For example, if the targeted platform is Windows and the problem is with registry entries, it should in all likeliness be tagged with registry. The fact that the purpose of the registry modification is uninstalling, is almost never essential to the problem.
