Can you call a cheeseburger a hamburger? I am eating self-made ones.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. See the FAQ for guidance on how to improve it.
Technically, a cheeseburger is a specific form of hamburger.
But, if someone asks for a hamburger and they get a cheeseburger, they will probably be upset at not getting what they wanted. That is, the term 'hamburger' usually is used for the specific plain version, not for any kind of hamburger, at least with respect to added cheese; a cheeseburger is not a hamburger.
So you can call a cheeseburger a hamburger in a burger construction manual, but not when accepting orders in a restaurant.
