Hello CA Dolfan,
Please read the Software Licensing Terms for your Office 2010 Pro Academic. Look in the first few papragraphs for the term "licensed device(s)." It will tell you whether you can install on one licensed device or two.
If one, you can install and activate Office Aca 2010 onto NB1. When you activate, if you are told that Office has been installed on too many computers, rerun the activation and choose telephonic activation, then do not enter or say anything into the
system which will shunt you to a live representative. Explain the crash and the move and they will activate it.
If two, you can install it on NB1 and the new NB. Same advice for activation as above.
As your Office 2010 computer is dead, look up the license terms here:

There is an entry for Office Professional Academic 2010 in the dropdowns.
