No, just any chain unconfirmed UTXOs can't exceed 25.
Well, ok, don'know enough detail here, but _some_ astroturfing method could be used (for good) to allow more tx's, no?
A single key can control multiple UTXOs, and due to memo tips most memo accounts usually do. So these could be juggled to mitigate the limit.
Btw, there's an unlinked page for viewing all your UTXOs -https://memo.cash/coins
