Is this a chafer beetle larva?

I found several 4cm long, plump white 'caterpillars' burrowing in my garden. An earlier answered question makes me think they may be larvae of chafer beetles. If you are familiar with those, please look at my photo a href="http://www.flickr.com/photos/28270165@N04/5603496109/" rel="nofollow"http://www.flickr.com/photos/28270165@N0…/a and tell me whether I am right.
