Names have zero effect for the AIs.

To protect your file integrity, you will want to create a modfolder.

Create a new folder, and call it "SamuraiModv1"
Inside there, it should have the same structure as your base SE4.
To mod the facilities.txt file, you create a "Data" folder inside "SamuraiModv1", and copy facilities.txt in.

Edit the copy all you like, and you don't have to worry about having to reinstall because you lost your unmodded game.

To play your mod, find Path.txt in the main folder with the SE4.exe
Edit that, and change the line:
Path := None
to
Path := SamuraiModv1

When you next run SE4, it will load your modded files instead of the originals.
For any needed files which you don't put it your mod, SE4 will use the defaults.
