Yes, you can check for spark from the coil by removing the wire from the distributor cap and install a spark tester directly to the wire. If you choose to use a spark plug to test for spark, open the gap up, it should easily jump a 1/2" gap and still have a blue spark. The only draw back to testing coil output using the coil wire, is if the coil wire is faulty, you won't know if it's the wire causing the no spark condition, or something else. Best to use a known good spark tester, instead of an unknown wire.
