Should I be alarmed by this NO JOIN PREDICATE warning?

I'm troubleshooting the bits and pieces of a poorly-performing stored procedure. This section of the procedure is throwing a NO JOIN PREDICATE warning

select    method =         case methoddescription             when 'blah' then 'Ethylene Oxide'            when NULL then 'N/A'            else methoddescription        end,    testmethod =         case methoddescription             when 'blah' then 'Biological Indicators'            when NULL then 'N/A'            else 'Dosimeter Reports'        end,    result =         case when l.res is null or l.res <> 1 then 'Failed'        else 'Passed'        end,    datecomplete = COALESCE(CONVERT(varchar(10), NULL, 101),'N/A')from db2.dbo.view ls    join db1.dbo.table l        on ls.id = l.id    where item = '19003'        and l.id = '732820'

The view ([ls]) calls a remote server (the remote query %41 on the right of the plan).

Here is an image of the plan:

I only ask this question because of this blog post and I want to make sure this won't come back to bite me later.
