Its safe to assume they are because they were both made by Power-FX

+Luka Megurine they're not, YOHIOloid is really just a vocaloid version of the singer YOHIO (not 100% I think) OLIVER is designed as a vocaloid and the only connections he could have to his, unknow, voice provider is the age (and kinda the outfit because it's based off a choirboy uniform) but they are like brothers c:

Tienes que ver Fullmetal alchemist o FMA Brotherhood {segunda versión apegada al manga} para entenderle

+deisi estár puedes buscar su versión en español, aunque originalmente la canción está en ruso si no me equivoco y se llama "Bratja" {Que la puedes buscar subtitulada}

exacto :v
