In a word, no. Rice is most of the times cooked in water whereas, according to wikipedia pilaf is cooked in an aromatic stock or broth. Pilaf is believed to be of Persian origin and it is much more than just boiled rice, since it absorbs all the flavors and nutrients of the broth. A Greek example of another type of pilaf is this chicken soup risotto which is usually served in Cretan weddings (the numerous rice grains symbolize abundance, fertility and good luck!).
