It's worth talking to an ergo specialist, but if you can't easily keep your wrists up it often means your broader setup isn't right - your chair is too low or your keyboard is too high (common on desks based on old designs.)
I've had carpal and nerve issues in the past, so I watch this a lot... generally you can drive the better habits simply by reconfiguring the work setup.
Been there, done that, sent the "specialist" on her way as soon as she started rambling about my aura. My issues went away with a switch to Dvorak years ago anyway.
But all of this is quite irrelevant when one is talking about the inherently non-ergonomic use of a laptop that only happens in meetings and hotel rooms.
If your ergo expert is talking about auras instead of measuring your dimensions and evaluating your posture, you need to find a real ergo expert. Even for ad-hoc use in meeting rooms and hotel rooms, a good expert can help you do a better job and protect your nerves. Anyone who works at a computer all day should probably go at least once a year, just like an annual physical.

In other words: This is how reality works. And here in reality, the buckle is annoying. Speculation as to its annoyance in an alternate reality is beside the point.
