There shouldn't be any issue by doing that.
In the background, you're spending an "Unspent Transaction Output" (UTXO) which will be used as an input of the transaction
and with it, create a new UTXO(s) which is the output of the transaction.

Basically, the input is a script the you've unlocked to spend coins and the output is a script that's locked coins from that input;
it's only shown as address in your wallet, so
TL;DR: When sending bitcoins, you're not actually sending to addresses.
