Does the Spanish language have any verbs whose perfect tense forms are based on a different lexical root from the infinitive form (by analogy with the Latin verb fero > tuli)?

In addition to the highly suppletive verbs ser and ir, some other verbs have a few non-cognate conjugations:

  • the past participle of matar is suppleted by morir in the passive voice: [fue] muerto
  • the impersonal present indicative of haber, hay comes from ha i (< ahí < ibī)

Some linguists also describe the different conjugations of caber ~ quepo etc as "partial suppletion".

    Interestingly, under certain circumstances you can still use ha, particularly in time situations: cinco años ha que hago algo, although I wouldn't call it interchangeable by any means – user0721090601 May 11 '19 at 01:55

It does, they are the irregular verbs, but amongst them the most irregular are the following:

"ir" in perfect past first person is "fui"
"Ser" in perfect past second person is :"fui"

responder uses —historically and to a limited extent today— the forms repuse, repusiste, repuso, etc.
