Well - this is not the scenario for the use of "if" but for "override".
The override property will only override the current content, if there is
some content in the overriding object. So you could do it like this:

temp.siblingMenu = HMENU
temp.siblingMenu {
    entryLevel = -2
    1 = TMENU
    1 {
        wrap = <ul>|</ul>
        NO {
            allWrap = <li>|</li>
        }
    }
}

temp.subpageMenu < temp.siblingMenu
temp.subpageMenu {
    entryLevel = -1
}

temp.mySwitchingMenu = COA
temp.mySwitchingMenu {
    10 < temp.siblingMenu
    stdWrap.override.cObject < temp.subpageMenu
}

This will generate a menu with the siblings of the current page in section
10 of the COA.
Then it will override the whole COA with a menu of the subpages of the
current page but only if there is content in the subpageMenu.
Just be sure to only wrap the TMENU and TMENUITEM parts but not the HMENU
since this would always return at least the wrap as a content.
