If the harmonic voltage is due to a distortec curent flowing in the load, then the addition of the capacitor will reduce the high frequency of the supply and can increase the harmonic current flowing in the load.
Most power factor correction capacitors have a maximum current rating of 110% of nominal. In ohter words, provided that the carmonic current (total) is less than 10% of the nominal current, there should not be an issue.
