Greasy meats don't do well on any inside cooking system...burning grease always creates smoke and vaporized grease.
No, all meat doesn't have to be deboned before cooking.
And if you are talking about a whole un cut chicken as a large piece of meat....I would guess it would be hard to get it done inside without over cooking on the outside....but not impossible.
A grill pan works on the same principle as does an open out door grill. Apply heat....meat cooks.
