So can a machine built entirely from discrete components. A VAX 11/780 had no microprocessor at all. Just a CPU built out of components.

Not quite - the VAX-11/780 relied on what was essentially a LSI PDP-11/03 as a general purpose glue processor (the “console interface board”) for the CPU initialization sequence, console and floppy I/O, and other assorted tasks.
