I don't work with memory-optimized tables so I searched the web for the answer. Two sources state that DBCC CHECKTABLE will return: "Msg 5296, Level 16, State 1, Line 86 Object ID 565577053 (object ‘InMemoryHekatonTable’): The operation is not supported with memory optimized tables. This object has been skipped and will not be processed." I have no reason not to believe it.
Ref. 1: DBCC CheckDB and CheckTable doesn’t check In-Memory OLTP.
Ref. 2: Comment 8. in Postponing Our Use of In Memory OLTP.
