Not really.

I don't see any striking differences between the trace output of a test
involving a lazy prereq from Bash or dash:

  $ cat t9999-test.sh 
  #!/bin/sh
  
  test_description='test'
  
  . ./test-lib.sh
  
  test_lazy_prereq DUMMY_PREREQ '
          : lazily evaluating a dummy prereq
  '
  
  test_expect_success DUMMY_PREREQ 'test' '
          true
  '
  
  test_done
  $ ./t9999-test.sh -x
  Initialized empty Git repository in /home/szeder/src/git/t/trash directory.t9999-test/.git/

  mkdir -p "$TRASH_DIRECTORY/prereq-test-dir" &&
  (
          cd "$TRASH_DIRECTORY/prereq-test-dir" &&
          : lazily evaluating a dummy prereq
  
  )
  + mkdir -p /home/szeder/src/git/t/trash directory.t9999-test/prereq-test-dir

  prerequisite DUMMY_PREREQ ok
  expecting success of 9999.1 'test': 
          true
  
  + true
  ok 1 - test
  
  # passed all 1 test(s)
  1..1
