  Yes, they can. They don't need to include their license with the work. When you buy a DVD, you don't get a copy of the licensing terms between the authors and the record company, either. Just because the CC license was included, that doesn't mean Elsevier is distributing the work under it. And in fact, there's a simple explanation: it's a license for the reader.

    How can one verify that a vendor has been licensed to sell a work if they don't include their license with the author? Maybe a street vendor has been licensed to sell the just-appeared-in-theater movie that they are selling?

A more valid analogy here would be "maybe the multiplex cinema selling movie tickets has been licensed to screen the just-appeared-in-theater movie that they are showing".
