Yes, ...and...
If you remove the spacer, the outer and inner ring can each use 9 out of 10 of the cogs on the cassette. You need to avoid the big-biggest combination, in this case to 50t outer ring with the largest cog. You also need to avoid using the small-smallest combination, in this case to 39t inner ring with the smallest cog.
I have a 105 triple with a 50t, 39t and 30t. I have a 12-27 10 speed cassette. I use the 50t when traveling above 24 mph for longer periods. If I removed the spacer, I could use the outer ring when traveling above 15 mph. I use the 39t from start-up to 26 mph. If I removed the spacer, I would stay off of the smallest cog and switch to the big ring at 23 mph.
When in the 15 to 23mph range, I would be able to use either chainring without a problem. This is the best reason for converting a triple to a double, IMO.
