Nope. Not even close. Steinways are hand built pianos, especially during that era. Current Steinway keysets are made by Kluge these days, and they will almost always require major forefinishing to fit into a 100 year old piano. Think trimming check blocks, moving fall board, installing capstans and backchecks and modifying action geometry to match the new parts. And you're almost always better off using the original action frame.

Subject: New Steinway keyboard and action frame for a 1923 S&S Model O?
Hi,
All parts are original except for the hammers, strings and key tops. These were replaced when the piano was reconditioned in 1983.
Steinway sells new keyboards and action frames. Am I correct in assuming that these are pretty much drop in replacements for the old parts? I anticipate minor adjustment of the action frame height in order to match the existing action elevations.
