Yes, you'd use the constant key reducer filter. You can use it two ways:
1. re-plot (bake) the animation and set it to use the constant key reducer via the key controls window
2. filter the selected bones' fcurves by going to the filter tab in the resources window.
Constant key reducer will remove any keys which are within minor tolerances of their neighbouring keys' y position in the fcurve editor.
