While Hinduism and Buddhism superficially appear very similar, they are in fact very very different.
Moksha is liberation, but this liberation is achieved by merging one's self with their atman, which is the essence of Brahman. This is essentially a spiritual association.
In Buddhism, nirvana is also a liberation, but there is not mention of divine essence ... only of waking up and seeing things clearly. Seeing as God is not involved in this, it cannot be a spiritual association.
