Can you get away with providing totally different content to US visitors and UK visitors from the same url.

Yes. This is perfectly normal and common behaviour. In fact Matt Cutts confirms this in one of his videos on Webmaster Help channel on YouTube. Without knowing the exact technical details it's hard to know whether there is a risk for sure or not. The problem you have is the fact that Googlebot may not act as a geo user and you may end up with US or English language content only in index. Sitemaps or site structure will be a handy solution in that case.
