I am wondering if it is possible to create a CNAME in one zone to

FYI you can try querying cname-example.fantomas.sk:
% dig +noall +answer any cname-example.fantomas.sk.
cname-example.fantomas.sk. 43200 IN CNAME cname-dest.fantomas.sk.
% dig +noall +answer txt cname-example.fantomas.sk.
cname-example.fantomas.sk. 43200 IN CNAME cname-dest.fantomas.sk.
cname-dest.fantomas.sk. 43200 IN TXT "this is an example of how CNAME
works"
% dig +noall +answer mx cname-example.fantomas.sk.
cname-example.fantomas.sk. 43200 IN CNAME cname-dest.fantomas.sk.
cname-dest.fantomas.sk. 43200 IN MX 10 cname-dest.fantomas.sk.
% dig +noall +answer a cname-example.fantomas.sk.
cname-example.fantomas.sk. 43200 IN CNAME cname-dest.fantomas.sk.
cname-dest.fantomas.sk. 43200 IN A 127.0.0.1
Can't find anything that says it will work, but can't find any thing
that says it won't, either.
For example, I have added in the zone file for dom1:
_acme-challenge CNAME _acme-challenge.dom2.com.
and then in zone file for dom2:
_acme-challenge TXT "thisismytextvalue"
Then, and more or less as expected, the following dig command fails
to return a record.
dig -t TXT _acme-challenge.dom1.com
is is supposed to work this way. If it doesn't, you have an error somewhere.
Are you sure that there's no other _acme-challenge.dom1.com record than the
CNAME?
