Yes, it is possible, however you will not be linking into Business Objects. BO is simply a reporting tool that sits on top of a separate database. Your database could be in any number of different DBMSs including Oracle, SQL Server, etc.
Your Business Objects reports will (probably) be based around a Business Objects universe, which will in turn be pulling data from a database. You need to open the universe in Business Objects Designer and check the Parameters dialog box (File>Parameters) which will give you the database details. You will then need to create a new ODBC data source object via Control Panel, which will allow you to connet directly to the database in MS Access.
