? about automatic HTC app updates and SD Card

[MBM7881]

i have a question about some stuff. this mornig i woke up to application updates that needed to be done on the Evo 3D. the ones that were updated were: Default Lock Screen, Rosie Utility, Watch, and Watch Install Recv. Yesterday it updated HTC Sync. Now these 5 apps are in my downloaded apps (under the settings/manage applications list not my actula app drawer). they give me the option to move them to the SD Card....and I did with the HTC Sync but i'm wondering if i can with the other 4 as they seem to be for the os and stuff. can i move them to the SD card without causing an issues to the phone? thanks in advance
