Short answer: No.

What you are trying to achieve is called Reverse Geocoding.

Explanation: Google's usage limitations specifically mention that they forbid the users from using the Geocoding API without displaying the result on the map.

Although there are no instructions as to where the map should be located on the page, and which requirements should it meet, the intention is quite obvious.

There are several alternative Geocoding engines. Try these:

Geonames

Bing maps

Yahoo maps
