want to ask if there is a way that I can display a field from another content type to a field of another content type
You can use the entity reference module for accomplishing your requirements.

On the "Courses" content type you will add a field type entity reference which refer to the "Course Schedules" content type. 

Then in the "Courses" content type Manage Display, You can choose that the referred node link to appear, I think you can also choose that the rendered node to appear.
