No desks have ever been in Boardwalk that I can recall - I've owned there since 1996. I do remember some 1-bedrooms in other resorts had desks, but they've been disappearing in renovations even before the most recent round.
For me, it's never been an issue as I've always used the kitchen table in 1-bedrooms to work from - and if that needed to be occupied, I'd use the stand-up coffee table top and the couch - or borrow one of the chairs from the table if I didn't want to sit on the soft couch.
I do light work when I'm at Disney, so I could see it being a problem if you're seriously 'working' as in 8+ hours, full duties, phone and computer and zoom calls, etc. I mostly spend a few hours on weekdays logging into my work computer, checking and responding to e-mails, maybe a few calls if a client asked a question, or asking co-workers to handle something for me. I rarely work longer than 9am-12pm, and maybe an e-mail check again at night when I get back from the parks.
