Yeah, kinda I guess.
The values you are supposed to uphold and the religious bits are different from Buddhism, but there's some similarities. There's also stuff about reincarnation in Sikhism too, but how it was explained to me is that a Sikh lives his life trying to make THIS LIFE better rather then striving for the rewards of an afterlife.
There's not much talk of heaven or hell, but lots about reincarnating until you can fully understand by living right to become one with Akal (which is the Timeless Form of God that exists in all things), reaching a kind of enlightened state where you are one with God and thus have transcended your mortal frailties and flaws.
One of the reasons Sikhism places so much emphasis on charity and living well and protecting people and keeping the world functional is because their religion states that the ultimate reward in life is found in THIS world and not some afterlife you automatically reach after you die, so you have to actively make the world better to achieve a state of Jivanmukta (liberation from the illusions of the world).
