Yes, if the wire is old and frayed or if it is rubbing against metal the wire could ground out and discharge into the engine block before it get to the spark plug causing the plug to misfire. If the contacts are worn or loose you could also get an intermittent misfire.

Were the spark plug wires replaced? Even a pinhole in a plug wire can leak enough spark to cause a misfire. Try swapping that wire with another similar length wire from another plug and see where the misfire is then.
