I think that could be true. Look at Amaltheia here:
http://www.etymologica.com/page2.htm. It lists amalos as meaning tender. This article:
http://sthweb.bu.edu/archives/index.php?option=com_awiki&view=mediawiki&article=Talk:Ancient_Macedonian_language/Archive_2 (and many others) list the meaning of amalos as soft.
Amalia is a common name in Greece, but I can't find when it came into use. I searched for the etymology of Αμαλία in Greek and found pages that list the Germanic origin. I can't find direct evidence linking Amalia to amalos.
