How to access the type" property of a parent element

Question

Is it possible to access a specific property of a parent element of a subtask?

What I'd like to achieve is to include a subtask in a query when e.g. the parent task belongs to a specific component, something like WHERE component="My Component" OR (type=subtask AND parent.component="My Component")
