Sollte mit TREP gehen. Theoretisch.

MOVE_ITEM_X [raw item ID] [coordinate]
MOVE_ITEM_Y [raw item ID] [coordinate]
MOVE_ITEM_Z [raw item ID] [coordinate]
These three commands can move items (NOT Lara, but other items, like enemies or boulders) on the map. But you can use it only with ACTIVATED items, or else their position will reset to defaults when you will re-load your game.
Raw item ID can be discovered with FexInspect program. Just open your level file with it and find desired item in the list and remember its number in the list — that is the raw item ID. Coordinates are, as always, TR4 global coordinates (equal to ones shown afterr «t» label, when you're pressing F1 key during gameplay).
