Did the astronauts "remove" the docking probe, the drogue of the LM, and related mechanisms from the CSM to enter the LM of Apollo 11?
After docking both the probe and the drogue were removed, extracted from the tunnel and stored somewhere. Here is the transcript from Apollo 11. Some excerpts:
055:19:49 Duke: Apollo 11, Houston. It's a pretty good show here. It looks like you almost got the probe out.
055:19:54 Collins: Yeah, it's loose now.
055:22:14 Duke: We can see the probe now. Correction, the drogue.
055:22:22 Armstrong: Roger. [Long pause.]
055:23:04 Armstrong: Okay. Drogue removal's coming next.
055:24:07 Duke: 11, Houston. Now it's a good view of the storage area under the couch. [Long pause.]
The pictures AS11-36-5382, 5383, and 5384 were taken shortly thereafter showing them both in the LM. As mentioned in the transcript they were stitched together by Jon Hancock to this:
