No. Vedanta follows Upnishads, Brahma Sutras & Bhagavad Gita and upholds insight into truth or ultimate reality Brahman. Devotion & surrender to God are common theme among Vedanta & Sikhi but differences are present. I will try to keep them short. I will be using Hindu Terminologies when mentioning Sikhi for ease of understanding. a.) In Advaita, Atma is completely Brahman, creation never took place, maya is inconceivable & beginningless. The Truth can only be known through Shruti Scriptures, i.e. Vedas. It is knowledge based. Sikhi is not Advaita because Atma is part of Brahman, it accepts creation of the reality, maya is neither beginningless nor inconceivable. Sikhi does not follow Vedas to find The Truth & is devotion based. Bhai Gurdas has explained the difference in his Vaar 1 Pauri 11. b.) Vishishtadvaita and Sikhi agree on devotion, creation being part of God, but are different because Vishishtadvaita is based on worshipping sargun personal deity / idol worship and mukti at the end of the birth. Sikhi does not allow sargun personal deity / idol worship and mukti is reached anytime while alive. c.) In Dvaita, Atma can never have proper union with Brahman and will remain eternally separate which Sikhi does not agree with. Gurbani speak continuously against dualism. d.) Shudhadvaita & Sikhi agree on devotion, everything is just Brahman, but in Shudhadvaita supreme God is personified as Krishna and idol worship is allowed. While Krishna in Sikhi is not an avatar & thus not worshipped, Sikhi does not allow idol worship either. e.) Bhedabhed takes inspiration from Dvaita & Advaita, Sikhi rejects Dvaita more. f.) Achintya Bhedabhed takes inspiration from Dvaita & Vishishtadvaita, Dvaita is a big no in Sikhi. *.) Vedanta- acts a base for Puranic Hinduism which came after Vedic Religion, Sikhi doesn't fall under any of those as it rejects authority of Vedas, Puranas, Epics or any other Hindu Book.
