In short, a LiPoFe battery can take more charge faster than a lead acid battery can, so any charging system that will charge lead acid, will be like a trickle charger for the LiPoFe battery and will not harm the LiPoFe battery at all. As long as the lithium battery and lead acid charger are both rated for 12V.

The electrolyte''s chemical reaction between the lead plates produces hydrogen and oxygen gases when charging a lead-acid battery. In a vented lead-acid battery, these gases escape the lead-acid battery case and relieve excessive pressure. But when there''s no vent, these gasses build up and concentrate in the lead-acid battery case.
