no you cant
and there is no " delete " button either
all you can do is mark them as anonymous
which will permanently delete them from your list of asked questions
and replace your username with the name "fau"
to do that click on your profile then go to the right hand side
in the box it says " my questions "
click on that
then mark the ones you want to as anonymous
you cant remove a quetion but what you can do is mark it as annonymous. that way no one will no its from you and itll be removed from your profile and added to your watchlist
