The information you have provided indicates that your laptop already has a 64bit compatible processor, which means that it should be capable of running the 64bit version of Windows 10.

You can download a checking tool here. It will analyse your machine, and provide all kinds of information.
You are looking for three things in the analysis results, and you can read about those here.
