Answering my own inquiry, it all works.  This laptop does indeed support 64GB RAM.  The 2230 SSD initialized, formatted, and functions.
Recently purchased this model and had a couple of questions: 1.  The second M.2 slot accepts a PCIe Gen 3 SSD in size 2230.  For some reason that size is not readily available, however Western Digital has SN530 1TB in 2230 and a few sellers on a well-known auction site has them.  The slot one has a Western Digital SN730 1TB for the OS drive.  Is the SN530 a viable option?  2.   The tech specs for the 7610 notes RAM is limited to 32GB.  The Crucial configurator says this model will support 64GB, noting tech specs are often current at time of printing/publishing.  Can the 7610 operate with 64GB with no errors or performance hit? TIA Sepp D.
