What specific interface is that? :)
An ActiveX control is essentially a simple OLE object that supports the
IUnknown interface (methods QueryInterface, AddRef, Release), the same as all
COM objects. It usually supports many more interfaces in order to offer
functionality, but all additional interfaces can be viewed as optional.
ActiveX Controls must also support self-registration by implementing the
DllRegisterServer and DllUnregisterServer functions.

Sounds like you've answered your own question :).
You are now talking about the differences between OLE objects and ActiveX
controls, but remember that was not the question. Not all COM components
are OLE objects.
I was pointing this out.

Microsoft say:
"Keep in mind that an ActiveX control is just another term for an "OLE
Object" or "Component Object Model (COM) Object."
