A client rebranded a few years ago and doesn't want to be associated with it's old brand name. He wishes not to appear when the old brand is searched in Google, is there something we can do?

The problem is there was redirection between the old branded site and the new one, and now when you type in the name of the old brand, the new one comes up. I have desperately tried to convince this client there is nothing we can do about it, dozens of news articles crop up with the two brands together as this was a hot topic a few years ago, but just in case I missed something I thought I'd ask the community of experts here on Moz. An example for this would be Tyco Healthcare that became covidien in 2007. When you type tyco healthcare, covidien crops up here and there. Any ideas? Thanks!
