My new top of the line (maximum options MBPro) struggles more to cope with large files and edits in Lightroom than my old one. Can the RAM be further increased to more than 16Gig?

If you didn’t buy the upgrade from Apple, no. If Apple didn’t make that option, no. This machine has ZERO upgradeability. All upgrades must be purchased upfront and requires Apple providing the option in the first place.

Apple, in its infinite wisdom, is telling you that you don’t need more RAM. There is nothing wrong with your Macintosh. Do not attempt to adjust the picture. We are contolling the transmission . If we wish to make it louder we will bring up the volume. Is we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image. etc., etc We will control all you see and hear https://www.youtube.com/watch?v=FCcdr4O-
