It will have the same proliferation risks.
A fusion reactor is an extremely intense source of neutrons. The neutrons can be used to transmute elements, e.g. to transmute cheap natural uranium or depleted uranium into plutonium 239, which can be separated easily (in comparison with enriching uranium) and it can be used to make nuclear bombs.
Besides producing plutonium for nuclear bombs, it is also easy to use a fusion reactor to produce any kind of dangerous radioactive isotopes that could be used in terrorist activities.
So no, a fusion reactor that uses the fusion reactions that are possible today will not be any safer than a fission reactor, from the point of view of the proliferation risks.
Neutrons are free. You can make a fast neutron source for a few million bucks today. Making a bigger one that can produce usable power is no big deal. The existence of fusion reactors makes absolutely zero difference to the question "who should have fissile material?" You cannot start or stop ignoring that question whether you have or don't have fusion reactors.
