So the if only reason given for why people think that Satan is a cherub is this passage then one cannot reference the cherub in this passage as proof that it's refering to Satan.
Some scripture that refer to Satan as some form of angel or dragon:
And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve.
2Corinthians 11:14-15
And there was war in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But he was not strong enough, and they lost their place in heaven. The great dragon was hurled downthat ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him
Rev. 12:79, NIV
Also, here's some commentary by Rabbi Tovia Singer on the subject:
For the Jewish faith, Satan's purpose in seducing man away from God poses no problem because Satan is only an agent of God. As a servant of the Almighty, Satan faithfully carries out the divine will of his Creator as he does in all his tasks.
Satan is one of the many angels mentioned in the Bible. It is worth noting that the Hebrew word for angel is malach, meaning "messenger." The same is true for the English word angel, derived from the Greek word angelos, which also means "messenger." Throughout the Bible, an angel is a messenger of God who carries out the divine will of the Almighty. There is not one example in the Jewish scriptures where any angel, Satan included, opposes God's will.
