Possibly not advisable, given that Toys 'R' Us has a long history of suing companies, all over the world, for what it sees as trademark infringement!
(They've taken Carpets 'R'Us, Guns 'R' Us, Adult 'R' Us, and countless other companies to court. They've also forced lots of independent traders, including many in the UK, to drop their use of 'R' Us in their business names by threatening legal action against them).
