I don't think so, I frequently steal from allies by besieging and assaulting a settlement they already have undersiege, not only does it force them to help but you get the settlement...

You can even do this to yourself...

In one instance I was besieging with a large crusader stack the crusade target. I brought up a siege engine stack after a few turns later and besieged with that too. I then used this non-crusade stack to lead the assault... Well I took the city but it was my non-crusade stack that did thus resulting in a canceled crusade because the target had been captured...
