the cornerstone of lean is "flow" removing of waste is to the end of achieving flow (time it takes to get sales to delivery). Toyotas system is predicated on the idea that for manufacturing THEIR product the touch time is way less the than the buffer/quueue times ( ie, the time spent adding value is small compared to the the overall time to get an order and get it delivered. Eliminating waste is a means to an end to cut into unecessary buffers and queues and increase flow based on the constraints of the system. In software there's a lot of applicable ideas, but it's not exactly the same and requires careful thinking around what your revenue model is and how you deliver software based on that. But the focusing idea is not the practices of lean but how to increase flow and build (reuse) practices around that.
