I think that's unlikely based on the design. Beagle 2 was in a flattened cylinder, a bit like a hat box, that was sealed shut to protect it on entry. After becoming stationary, the 'lid' would flip open and the round solar petals would unfurl.

If the lid opened allowing one of the petals to unfurl and break off during landing I wouldn't expect the rest of the petals to unfurl perfectly.
