Yes. And yet ... there's a trade off to consider. e.g. for asbestos, occasionally the best choice (depending on the location of the asbestos containing material and its current condition) is to leave it in place and secure it / envelop it. In some cases, removing the asbestos bearing material entirely would increase the chance of it entering someone's lungs. I believe this kind of tradeoff can be applied to lead bearing materials too. Of course, there's also the peace of mind factor. And that's valued differently by people. Given a high enough budget, removal can probably always be done safely. But sometimes the required budget is awfully high.
