Whether it can affect your system depends upon how high your level is. If it is all the way to the top of the neck of the reservoir filler hole that might not allow room for the coolant to expand after engine shut down and heat soak of the coolant in the block, with the resultant pressure stressing the sealed system.

When I needed to adjust mine I stole my wife's turkey baster and sucked out the excess coolant out until the correct level was shown by the stick, and then put the baster in a marked sealed bag with my other auto supplies for future use. (And of course I purchased a new baster for my wife well before Thanksgiving).
