No. VY is not in oneworld. A BA-marketed flight operated by VY is not considered a oneworld flight.

oneworld Lounge Access for Frequent Flyers By Tier Status
Enjoy exclusive access to premium airport lounges around the world with oneworld Emerald or Sapphire frequent flyer tier status. Members of oneworld airline frequent flyer programmes with the equivalent of oneworld Emerald or Sapphire tier status can use lounges offered by oneworld airlines when departing on any flight marketed and operated by any oneworld member airline, regardless of cabin class being flown (exceptions are noted below).
