Absolutely, although those definitions of C.Eng are rather out of date - there is no proscriptive definition of the time required in further training or professional practice, merely a specification for the competences that must have been exhibited (this is where CEng and PE diverge). Also the degree is not mandatory - it is the "standard route". The standard requires "Underpinning knowledge and understanding to the level of an MSc supported by a BSc" but it allows that UK&U to be achieved and evidenced in ways other than the actual degree(s). That is the "individual route" (in that it requires individual assessment of evidence rather than acceptance of a standard qualification).
The last time I had the query run was 2 years ago, but it suggested that of the registrations between 1990 and 2018 only 20% were achieved by the standard route. There was a time when you could sit the Engineering Council exam as a means of verifying UK&U, but I believe that was formally terminated in 2011.
