Yes he is, he is really jewish.
The surname "Fowler" is of English origin, typically occupational, referring to someone who caught or sold birds. It is not specifically a Jewish name, but like many surnames, it can be borne by individuals of various ethnic and religious backgrounds, including Jewish families. Jewish surnames often have distinct origins related to Hebrew or Yiddish language, while Fowler does not fall into that category.
Eliot Spitzer's wife is a Southern Baptist, and he is of Jewish descent. I found a picture of their family going to church, so I would guess Christian.
Of the main characters Howard Wolowitz, Dr. Amy Farrah Fowler, Dr. Bernadette Rostenkowski, Leslie Winkle and Stuart Bloom are Jewish.
