In order for a regular LEGO to attach to one of the more modern Technic sets, there must be a peg connection located somewhere on the Technic set. Unlike regular LEGOs which have an attachment feature for easy connection to other pieces, the Technic line was created to be its own independent entity with unique features and details. For this reason, it’s highly unlikely that the Technic sets can attach to a regular LEGO unless there is an obvious peg connection. By reading Amazon reviews, you can also find the answer to this question regarding a specific Technic set you are considering.
