Is there a way to whitelist words in the spelling dictionary so that they will not be flagged as mispellings?
Can this be done for individual notebooks, all notebooks or both?

You can monkey with the spelling correction settings in the Options Inspector. You can make changes that affect the either the current notebook (Selected Notebook) or for all notebooks (Global Preferences). Click on the toolbox icon (red arrow below). For global changes does to take effect, Mathematica must be restarted. For notebook changes to taken effect, the notebook must be reloaded.
The second part of the duplicate question describes the way to add custom words to the dictionary:
file = Import["words.txt","List"]
SetOptions[$FrontEndSession, SpellingDictionaries -> {"CorrectWords" -> file}]
Replace \$FrontEndSession with \$FrontEnd for a permanent global setting.
