No
Rigidbody interpolation is performed after the next frame's FixedUpdate() when using Rigidbody2D
How to reproduce:
1. Open the attached “rb_interpolation_issue” project
2. Open the SampleScene and enter Play Mode
3. Observe the Console output
Expected result: the position of the Transform is updated based on the Rigidbody’s position before the start of the next frame
Actual result: the position of the Transform is updated between FixedUpdate and Update
Reproducible in: 2021.3.33f1, 2022.3.15f1, 2023.2.4f1, 2023.3.0a18
Reproducible on: Windows 10, Windows 11
Not reproducible on: No other environments tested
Notes:
* Also reproducible in the Player
* The project contains two logging scripts, one which has its script execution order set before Default Time, and another script that is set to execute after Default Time. This way we can check what is happening between the different Update functions. Lastly, there is a script that moves the Rigidbody in every frame.

Resolution Note:
There seems to be a misunderstanding on what MovePosition should be doing here and when things get updated.
