Basically, not. When you start an application component registered within another application manifest file, a new process for this component will be created (if not already running) and the component will run within the newly created application process. Although for a user it looks like it's running within your app.

App Components (at the end of the section) might clarify some aspects.

Edit (with respect to the comments):

You can't add a new UI control (talking about Activities) to the component of the newly started (or brought to foreground) application by the reason of running on different process.
