It could - on rather primitive level. Russo-Japanese War era, roughly. Even Deryer table without electric data transmission for its output would be severely handicapped.
You assume that you can map directly from historical performance to that of modern performance using the same technology. Voice tubes can convey data between systems. Once transmitted the data can be entered into other mechanical computers can compute the correct training and elevation for that gun/turret. Gyros that are required for torpedoes to work also would be used for gunnery.
Training (dotters), naval tactics, gunnery TTPs all improved to greatly increase the effectiveness of naval gunnery separate from technological advancement. From 1903 to 1906 the USN improved hit percentages from 40% to 77% and improved the ROF heavy guns through improved TTPs and gunnery training.
The output may be degraded without electric data transmission but using the
same level of technology but with improved, training, TTPs and equipment design a navy from WWII would have been far more effective than it was during the Russo-Japanese war era.
So the probability that steam powered torpedo boats surviving to engagement range seems unlikely in the face of QF guns mounted on torpedo boat destroyers where local control is adequate for the expected engagement ranges between lighter units.
