Although most times we make a distinction between the goal of yogis and jnanis(paramatma and brahman), many present day yogis actually follow sankara's advaita as their philosophy. For them merging into brahman and paramatma isn't different as brahman is the only substance.
Actually sankara himself said that jnana without yoga(devotion/meditation) cannot lead to liberation neither can yoga(meditation/devotion) without jnana(knowledge). Many yogis actually meditate on the impersonal brahman or some light rather than four handed visnu form corresponding to paramatma. Should we consider only yogis who are meditating on four handed visnu forms to be the only yogis who are meditating on paramatma? Actually in S.B even lord siva is addresses as paramatma and source of brahman in 8th canto.
Also I wanted to clarify one point, does giving up results of fruitive activity constitute karma yoga if results are just given for charity not for krsna. Can karma be called karma yoga without explicit connection to krsna, and similarly jnana be called jnana yoga without explicit connection to krsna. I was just seeing if we see any difference between a person on jnana marga and a person who is a jnana yogi

I believe the answer to all three questions is no.It is the consciousness and intention behind the activity that makes it yoga. And there may be varying degrees as well.
