When I attempt this I get error 000224: Cannot insert features - which suggests that some of my feature types don't match-up. However, all the feature types do match. To assure this I use schema type "NO_TEST" and join using the field map.
The short answer is yes, you can append features from in_memory to a GDB. There is something else going on. Are they different feature types, or something else obviously different between them?

Feature types are the same - polygon. The only notable difference are alias names in one feature class and not the other, but if that is an issue it would nullify using the field map.
Darren's reply proved correct after I replaced the target feature class with an export from the in_memory feature class. The schema type "NO_TEST" option still dropped some attribute values but was resolved by switching to "TEST".
