Yes. If you both take an autosomal test you will see whether it is feasible that you share a grandfather. I would recommend that you start by testing with AncestryDNA. You can subsequently upload the results to other sites that have a chromosome browser to get more information about how you match each other.

If you both test ancestry will show your relationship level as 2nd cousin if only grandmother in common ( same quantity of DNA for full first cousins)

First cousins level if both grandparents the same

The amount of shared DNA should be betwen 553 and  1225 cM, if you are 1st cousins (shared grandparents). the various testing sites vary in the amount but the amount shared should be in this range.
