You're referencing marketing material. All marketing material is to sell the product, usually to a somewhat targeted subset of the buyers. Looking at their sales, and around any office, their marketing, and "Pro" products, appear to be extremely appealing to a large range of professional users. I think this shows that their "Pro" label is appropriate. I'm having trouble understanding why you think it isn't appropriate.

Do you have a notebook in mind that is worthy of a "Pro" label, so I can see what you're baseline is?

Should they buy the Air, or pay the premium for the Pro? After all, they're "hardcore tech" people.

Do you have an example of a notebook where a "Pro" label would be appropriate, as an example, so I can understand where you're coming from?
