Is it safe to use a MacBook in a slightly tilted position?
It shouldn't harm your mac in any way so. At my workplace my Macbook is tilted. The only problem I can foresee is that since it's a wood base and there's no holes it may cause the macbook to overheat ( this is the worst case scenario). My workplace has a titled setup that tilts the mac to keep it cool. Tilting your laptop is good because it prevents overheating and its better posture for your hands.
