Yes, in principle life can form on any suitable planet.
Explanation:
Stars in any form of galaxy are quite well separated except possible at the galactic centre. The only effect which can affect life is if a star goes supernova within about 10 light years. The radiation from the supernova could eradicate any life.
The requirements for life, as we know it, are a planet at the right distance from a main sequence star with the right combination of chemical compounds.
As long as the life bearing planet's star isn't within 10 light year of a star which could supernova, then life can flourish.
