Yes, absolutely! 

Under the Advanced Search Tab, you can easily search by a company's headquarters location, which we call 'HQ Location'. You have a few options. You can either type in the city, state, country, or region (for example, 'San Francisco Bay Area' or 'California')

Or, if you are not sure what label might be associated with the location you want, you can find a different company in the area you are searching, and click on the location link in their Headquarters Location section to run a search for other companies in that area.
