I believe the evidence is there which justifies CB being the prime suspect in MM’s disappearance as far as SY and the BKA are concerned.
That compelling evidence exists, is further compounded by the fact that the PJ have made him an arguido.
This is a seriously important development. At one time concrete evidence was not required to do this, all that was needed was a policeman’s gut reaction or unsupported theory. This all changed with the introduction of changes to Portuguese law in September 2007.
As indicated here -
Carlos Pinto de Abreu, a Portuguese lawyer on the McCanns’ defence team, said that under Portugal’s new penal code, police must have more than just suspicions to make somebody an arguido.
"On September 15 a new procedural penal code was introduced making it necessary for there to be evidence against the citizen before they could be made an arguido.
"Before this date it wasn’t necessary. You could be made an arguido without actual evidence against you," he said.
"Maybe that is why the investigation took the turn it did - why they were named arguidos eight days before the new laws came in," said Mr Pinto de Abreu.
His comments followed those of Fernando Jose Pinto Monteiro, Portugal’s Attorney General, who recently admitted the McCanns may not have been made suspects under the new laws.
"At the time when the McCanns were made 'arguidos' the law did not demand justified suspicions. I do not know if they would be (arguidos) in light of the new Code," he said in an interview with the Portuguese magazine Visao.

This change in the law further substantiates the fact that evidence led to SY and BKA making CB their prime suspect, but it led to the PJ also declaring him to be prime suspect for them too. I think claiming “"strong indications" of the practice of a crime.” is indicative of that.
And on balance allows me to answer the question you ask in the affirmative.

On 3 May it will be 15 years since Madeleine was reported missing and under Portuguese law it would no longer be possible to declare someone a person of interest beyond this date. Declaring someone a person of interest is a necessary step to any criminal charges.
In its statement, though, Portugal's office of public prosecutions said the move was not driven by timing, but by "strong indications" of the practice of a crime.
