Hi Paul -
The simple answer to your question is YES! I have personal
experience (it wasn't a barrel of fun) on having some low residue
fluxes work and not work with palladium finishes. The use of an inert
environment can be an advantage but is not necessary. Palladium has a
slower dissolution rate than what you typically expect and therefore
you may need to adjust your solder reflow profile to accommodate this
change. It is reasonable to expect that you should get the same solder
joint geometry and appearance that you have been getting with Sn/Pb
but palladium is very flux dependent - try what you are using now and
also talk with you flux supplier on what they would recommend.

We have a vendor who is changing the metallizations of its components
to palladium from tin/lead.
Has anyone had problems with this?
Are there problems with no-clean fluxes?
