If sanded properly, it is okay to install porcelain tile over laminate

Also, can porcelain tile be installed directly onto solid oak wood?
Oak has been part of house for 25 years.

Ideally, I would use 1/4" backer board, but 1/4" thickness is still
too much in this situation.

Thanks.

yes. use mastic. heavily scar the laminate

no. wood moves too much with changing humidity
