No, a quesadilla in enchilada sauce is not different from an enchilada in any way, form factor or otherwise. A cheese enchilada is a fried tortilla filled with cheese and coated in enchilada sauce. By the time you've added enchilada sauce to a quesadilla, you've already completed the process of making an enchilada.

There is a podcast dedicated to such food related pedantry called "A Hotdog is a Sandwich." Pretty entertaining.

Would you really call it pedantry to object to someone saying "for an even better cheese pizza, try sprinkling pepperoni over the top"?

As a pedant myself, I would say yes!
