No, not currently. This is by design - the Evernote team feels that different people have different organizational styles and needs, and may want to organize their information differently from coworkers - so they don't want to impose a particular structure on others that they didn't choose. (I'm not saying I necessarily agree with this design, but wanted you to understand it.)
You didn't mention which platform but since 6.0..3 is a Windows version (Mac is on 6.6), I'll assume Windows.
There's no one-step move to Business but you can copy to Business and then delete from Personal.
To do that, select the desired note or notes in the notes list, then right-click and choose Copy to Business... from the context menu. Then you can just hit Delete to remove them from their current Personal notebook.
