If you're using Lawson's OLE DB component to build reports in Crystal, can you also integrate data from other databases (non-Lawson) with the objects available in OLE DB? Basically can you join a database table from a non-Lawson database with a Lawson database table available in OLE DB?

No, you would need to have multiple data sources within the Crystal Report (which you certainly can do...), but you cannot join within the OLE DB datasource to another database.

and you would have to log in to both (or at least code the login to each source)

I was able to link an MS-Access data base to the Lawson OLE-DB tables.

Also Lawson has said in the past that will not support any issues of combining non-lawson tables outside lawson schema to lawson tables.

That is true--you can create reports in Access as well as Crystal that combine data from Lawson (either via the OLEDB provider or a native ODBC connection, etc.) with non-Lawson data. However, your JOINs will not be done within the database--they will be done via Crystal or Access, which, depending on the data, can be a huge performance issue.
