I'm pretty sure that Lucius Malfoy was Lord Malfoy in canon.
The canon Potterverse showed no signs of being semi-feudal though. I imagine that he was a lord in much the same way that present day Lords of the Commonwealth are, ie. upper class but without meaningful rights over the rest of the population.
Edit: a google search for Lord Malfoy doesn't appear to bring up any text results from canon, but the potter wiki describes him as "aristocratic".

You would be wrong.
Edit in response to your edit: He is "aristocratic". He's rich, he lives in a manor, he carries a cane, and he's a pureblood. He's just not a lord, or any other sort of noble.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
