A hook is a specific place in a method that offers some options to 
callback functions (eg alter the processed data, cancel the "default" 
action"). What these options are and what data the callback gets is hook 
dependent.

A service is a completely different thing. A service provides an 
abstract API for some task. So the calling code does not have to worry 
about the actual implementatoin of the task (eg when the service is 
implemented by native OS executables or by different PHP extensions).

I hope my answer made clear that this is not possible.
