Almost certainly, there is some way of using a third party (possibly commercial) component to call a DCOM component.
But I wouldn't consider it a sound way of building an application. Why not port the COM class to a Linux app, perhaps invoke it from the CLI. Or consider writing a simple HTTP-based service on win32 to call your component's methods.
What is the use case? What does the component do? Is it internally or externally developed?
If you're thinking about using any MSOffice components, forget it. They're not reliable enough for production use (even on win32 normally).
