Generally, NO. Vinegar is approximately 3% acetic acid in water, which is immiscible in oils. There may also be some reaction between the acid and the oil components that could render either or both of them less effective for any dermal application. Also generally, dilution of anything simply mitigates some of the effects, it does not eliminate them. Thus, I would be very careful of any concentration of acid contact potentially with the eyes - even if the surrounding skin would not be adversely affected.
If something is a potentially harmful compound, care must always be taken when using it at any concentration. You might prefer to apply the vinegar and oil ointments separately as part of whatever regimen you are following.
