After summoning an armorstand with working gear and a correct command, with an item in the offhand, it cannot be removed.
Steps to replicate:
Summon an ArmorStand with an offhand item
Attempt to remove it
No such luck

@McDic I meant removing by hand, not by command.
@Kumasasa I'm not at my computer right now... I'll get it to you ASAP.
I removed successful.
/summon ArmorStand
/replaceitem entity @e[type=ArmorStand] slot.weapon.offhand stone
/replaceitem entity @e[type=ArmorStand] slot.weapon.offhand air
