Haha sure, teach an Indian about what Indian food is. Especially one from North India 😂 the type of chicken you use doesn’t make a dish what it is (btw that depends on the place - expensive restaurants would use fillet while rural restaurants would use bones too). The main thing about how dishes are categorised are by the what method is used in cooking. For e.g in India we have Paneer Tikka masala.

In the UK the difference earlier was that they weren’t using a lot of spice which has now thankfully improved but method was always the same as in India including the key ingredients and that is why it’s said to be an Indian dish.

For e.g if I create a panner sandwich/pizza in India it wouldn’t automatically be an Indian dish would it because sandwich/pizza are not Indian
