Hello cubs8282,
The Product Key on the Certificate of Authenticity (CoA) on the bottom of your laptop is for the Windows Operating System only. This Product Key is only for the installed Windows and should not be expected to activate any version, edition, or Trial of Office or Office component programs such as Word 2007.
In order to continue to use Trials of Office or individual component programs such as Word 2007 past their Trial expiration dates, you have to purchase a perpetual license for Office or individual component programs such as Word 2007 in the form of a perpetual Product Key. Please see this Office Help article for more info: http://office.microsoft.com/en-us/help/HA101936151033.aspx
