Why would you want to? Buy a REAL(tm) touring bike and go on a tour and you'll easily see what I mean.
On the Pacific Coast Highway there were a lot of young guys riding racing bikes and trying to tour down the coast. They were making it but it was very hard for them and they were living very spartanly since they couldn't carry everything they wanted and their bikes weren't geared properly and racing position just kills you on a long tour.
So I think that answer is - yes you can but you'd be crazy to do it. I could almost guarantee that you'd never tour again.
