Yes, but...

The points need a particular dwell time to optimally charge the 
coil.  The magnetic field must be sufficiently strong to produce a 
spark of proper size.  Too little dwell causes insufficient 
spark.  Too much dwell doesn't leave enough time for field collapse, 
also making an insufficient spark - it may contribute to coil overheating, too,
