Once someone offers up the replacement name so that we can continue to talk about what "object-oriented" referred to 40 years ago — and still refers to today, sure. Nobody cares about the exact letters and sounds.
But, until then, no. It is still something we regularly talk about. It needs a name. And lucky for us it already has one — and has had one for 40 years.

How does it not cover it?

Polymorphism? That was never mentioned. Let me reiterate the definitions:
- Imperative: Plain functions (C, Fortran, Pascal).
- Functional: Functions with encapsulation (C++, Java, Haskell, Erlang).
- Object-oriented: Message passing (Smalltalk, Objective-C, Ruby, Erlang).
Let me also reiterate that there are other axis of concerns. Imperative, functional, and object-oriented are not trying to categorize every last feature a programming language might have. Mutable/immutable, or polymorphic/monomorphic, etc. are others concern and can be independently labeled as such.
> Perhaps, but broadly speaking people agree that C++ and Java are OOP
Many do, but just as many hold on to the original definition. Try as you might, you're not going to find a common definition here, I'm afraid. If you want to use the term effectively, you're going to have to explicitly define it each time.
