Select 
    case when count(*) = 0 then 
        'No rows' 
    else 
        'Has rows'
    end 
FROM
(
   Select * from @table1
   UNION ALL
   Select * from @table2
   UNION ALL
   Select * from @table3
) t

UPDATE

This makes sure all of then have at least one row and fail if any of them does not have record

Select 
    case when count(*) = 0 then 
        'No rows' 
    else 
        'Has rows'
    end 
FROM
(
   Select top 1 1 found from @table1
   intersect
   Select top 1 1 found from @table2
   intersect
   Select top 1 1 found from @table3
) t
