Hi, understand that it's advisable not to change lenses in extreme cold weather. But is it still fine to change in the open for temperatures ranging 10-15 degree Celsius?

Good advise from National Geographic, when shooting at sub-zero temperature.
Tips for Cold Weather Shooting From Cotton Coulson and Sisse Brimberg -- National Geographic
I think the main thing about changing lenses in such cold environment outdoor was more on, you will cause moisture or condensation inside the camera body due to the difference in temperature from the ambience to the body.
Another nice site to read is,
Cold Weather Photography - How to Take Photographs in Cold Weather
Actually I have not been to these type of places... but I would believe that in any sub-zero condition, any water vapour or moisture that are on the body of the camera and lens will freeze and become ice (thin film of ice), thus it would cause the lens that are already being attached to the camera body very difficult to be remove (theoretically).
As to temperature at around 10-15 degree, theoretically, it should not be a problem, however there is the condensation issues that might be a problem, because of the difference in ambience temperature and camera body temperature. it was like, when you are in a very cold air-con room, and once you walk out of the room and into warm outdoor temperature, your spectacle will fogged up as condensation happen.
Taking that theory to your camera and lens, the interior of your camera are warmer than the ambience temperature, thus when you remove your lens and thus expose the interior of your camera to the outside temperature, it will rapidly cool the interior of the camera. However as you insert a new lens to it and started shooting, temperature will rise rapidly thus causing condensation. (anyway, those are all theory, not sure how the actual thing works).
Hope it helps.
