The google adsense code contains a reference to a javascript file. If I have 3 ad units on a single page, can I remove this reference from the other two because it is just the same. Will it violate the "don't manipulate the code" rule of google adsense?

Best to let Google do its thing without manipulating the code.
As this support page mentions, Google will optimize based on your pages:
