'In my recent interaction with customer, I was asked if linked server can be created to an availability group listener? My immediate response was “Yes”. Next question was immediately thrown at me that if they can redirect this listener to secondary replica? This time my little delayed response was – Yes. Provided we use proper connection string.

 EXEC sp_addlinkedserver @server = N'MyLinkedServer'
    ,@provider = N'SQLNCLI'
    ,@srvproduct = N'SqlServer'
    ,@datasrc = N'MyListener'
    ,@provstr = N'ApplicationIntent=ReadOnly'

…and it was not working as they expected.'...
