Technically, yes - the option is already available (at least it is on later versions of phpBB) but for use at an administrator level only.
Likewise it's feasible to write something (again, for administrator use only) to trawl through all the posts and replace a specific user's posts with "redacted" - but the fun starts with simple quotes and rapidly gets unmanageable with nested quotes. Nested quotes would need to be included because otherwise, the redaction is somewhat futile.
But even then it would still result in many threads losing their flow and meaning by having parts removed so this would be another reason why such a function is unlikely to be used, even if fully implemented.
And as hyperlexian points out, moderators wouldn't be allowed to mass delete posts because of the huge side-effect this would have on the whole site - it's outside our remit.
