in google, probably not. Their ranking system is based on a lot of things, like how often their spider visits your site(not very), how many external links you have, how many other sites link to your site, what your site's pagerank is, how much you pay them, how good your keywords are, what your description is, what keywords are entered by the person searching... For you to do that, you would have to make your link more relevant for the search term walmart than walmart's...(good luck with that one) Now if it were a search for "retail store", you might have a chance. Anyway, it's pretty tough do to in my opinion.
