Make last word of teaser a link

To answer your second question first:

Is drupal capable of this?

Drupal is capable of doing virtually anything. However, it does not to what you're asking by default.

Regarding your feature request, I think it's too specialized to put in a general-use module like this one. In other words, I don't think very many people will need this feature.

There are many other ways to do this you want besides adding it to this module. If you have some programming experience, you can make your theme do this or create a custom module. If you aren't a designer or developer, you can manually make the last word of your teaser a link by editing the node "summary" or by finding a module that gives you exact control of a node's teaser.
