Yes. They both use the A340E. Which is different than the A341E, used in the LS/Celsior. The A340E uses different gearing and valve body, but is similar to the A341E.
The Toyota A340E transmission found in the 1995 Supra and the 1994 Lexus SC400 are similar but not identical. They may have differences in gear ratios, shift points, and programming to suit the vehicle's characteristics. It's recommended to consult a professional or look up specific technical information to determine compatibility for any specific use case.
Really not a good idea unless you have a transmission malfunction. Check/change your transmission filter, and add a few quarts of Toyota ATF-III.

How do you install a oil pan gasket on 1995 Lexus sc400
I use the Denso plugs in my SC400
Yes they will
I believe there might be clearance issues along with transmission mating difficulty. A swap gaining popularity is the 1uzfe 4.0 liter all aluminum V8 from the Lexus sc400. There is ample information available on pirate4x4.com
You can reset a maintenance light on a 92 Lexus SC400 by disconnecting the battery. Leave it disconnected for 10 to 15 minutes.
