The Short Answer: No, it is currently impossible for an unequipped item to exist in a container or on the ground with that specific text, as the game’s engine now triggers a "delete" command as soon as the item is moved or updated if its remaining duration is below the minimum threshold (typically 1 or 2 seconds).
The Timeline of the Change: You are correct that the Summer Update 2022 was the turning point. While the official patch notes focused on the "Quality of Life" side (showing timers in containers), there was an unannounced change in the backend logic:
Pre-2022: The "will expire in a moment" state was a static text description assigned to an item when its internal timer reached zero but the "decay" tick hadn't processed yet. This allowed players to move it to a backpack, effectively "freezing" the item in that state because, at the time, items only decayed while equipped.
Post-2022: With the introduction of Total Remaining Time being visible everywhere, the server had to synchronize the decay of all timed items regardless of where they were. To prevent "ghost items" (items with 0 seconds that still occupy a slot), CipSoft implemented a hard check: if an item's duration is <2 seconds and it undergoes a state change (like being unequipped or moved), the server immediately flags it as expired.
Why you can still see it while equipped: The text "will expire in a moment" is now essentially a UI tooltip overlay for the equipped slot. Since the item is already "active," the server allows it to exist until the very last millisecond of the animation. However, the moment you break that "active" state by pulling it to a container, the check is performed, and because the value is effectively rounding to zero, the item is deleted.
Conclusion: Unless someone has a "bugged" item in a depot from a server save prior to June 2022 that hasn't been touched or moved (which is highly unlikely due to how item IDs are updated during patches), those items are gone. Modern Tibia logic treats "below 2s + unequipped" as "non-existent."
