You can't use a variable as database name and/or server name and/or table name. If you want to pass any of these names as parameters you are forced to use so called dynamic SQL:

CREATE PROCEDURE dbo.prueba151106
@base varchar(20)
AS
BEGIN
   DECLARE @cmd varchar(4000)
   SET @cmd = 'select * from [CPSI-SERVER].['+@base+'].[dbo].[certificados]'
   EXEC (@cmd)
END
