In addition to what the other person who replied said, ignoring that iOS/Android/iPadOS is far more secure than macOS, laptops have significantly less hardware-based protections than Pixel/Samsung/Apple mobile devices do. So really the only way a laptop in this situation would be truly secure from LEO is if its fully powered off when it’s seized.
ARM/M1 macOS took their hardware platform from iOS. TEE, signed/verified/readonly system files, etc. They are similar in security now.
