The majority of maintenance manuals are customised for a specific fleet, i.e. specific to a particular airline.
That way Boeing only provides information that is applicable to those aircraft and even with a given manual you need to be able to filter on applicability to ensure that specific maintenance information is applicable to a specific aircraft.
Having worked with airlines using Boeing maintenance data, the position pre-B787 was that the maintenance manuals were owned by the airlines but that Boeing were responsible for the original content. Boeing seem to be trying to change that for the B787, possibly in an attempt to get all B787 customers to use their Maintenance Performance Toolbox authoring/consultation tool instead of being able to use third party solutions or even Airbus's Maintenance documentation solution
So back to the original question, the answer is Yes , if an airline gives it to you, or No if you go knocking on Boeing's door.
