It really depends on your definition of balanced and how bad someone is at sharpening.
The blades are torqued down on there, if it’s a combustion engine mower, nothing’s you do to this blade sans taking an inch off is going to make much more vibration than the motor will itself.
The biggest worry is that you put enough vibration into it too cause it to loosen the blade.
If you’re even half reasonable sharpening you’re just taking off a fraction of a gram.
